Beschreibung

While commonly machine learning models make a single prediction, some predictive tasks require the assignment of more than one label for each instance. Furthermore, for some of these problems the labels have a hierarchy, i.e., they are structured in the shape of trees or directed acyclic graphs.  For  this specific class of problems, as far as we know, there is not a library with generic implementations of these algorithms available for users to quickly train and evaluate multi-label local hierarchical models on different application domains.

Therefore, within this seminar we aim to extend the local hierarchical classification library HiClass [1] to add support for multi-label classification, using real data for evaluation.

Learning objectives:

• You will improve your skills to develop efficient code;
• You will practice the test driven development technique;
• You will learn to plan and implement generic algorithms for hierarchical machine learning tasks;
• You will deepen teamwork skills;
• You will acquire the ability to contribute to open-source projects.

Voraussetzungen

You should have some previous experience programming in Python, familiarity with test driven development and other software engineering best practices as well as machine learning methods and libraries, in particular scikit-learn. Good knowledge of English is required to understand and discuss the assignments.

Leistungserfassung

Grading is based on multiple factors concerning the project success, including:

• Written report  (80% overall, structure 10%, code quality 40% and documentation 30%);
• A presentation due at the end of the semester (20%).

We will provide close support and regular feedback.

Termine

The first session will be on 24.10.2022, from 09:15 - 10:45. If necessary, the following sessions can be changed according to students' needs.
